Scene Construction Operators

Spatiotemporal projection: S.project(X1,X2,...,I)

Yields a new version of S containing only the specified objects and only information for the specified time interval.

Special cases:

  • S.project(Objs(S),I) gives a clip from a scene

  • S.project(objs...,IS) eliminates some objects

Overlay: S1.overlay(S2, ts)

Combines scene graphs, with all S2 motion starting at time ts after the start of S1.
